useful Improvements in Steam-Cookers, of

which the'following is a specification.

My invention relates to steam cookers, or apparatus used for thepreparation and treatment of large quantities Of cotton seed, fish, orsimilar materials, to be subsequently operated upon in oil presses.

The objects of my invention are, rst, to so construct andl arrange theparts that the steam or cooking medlum can be so regulated, that thetemperature and steam can be cont-rolled and modified at any one of thedifferent sections of the cooker independent Of the other sections, andWithout it being necessary to stop the apparatus or effect the feedingofthe material into the apparatus, or its discharge therefrom. Second,to provide means whereby" the Operation can be made a continuous one andthe material fed through the cooker uninterrupted and of varying speedsif so desired.` Third,

to so arrange the parts of the cooker so that access may ibe readily hadto any of the parts in order to quickly examine the same and makenecessary adjustments, or repairs, or replace broken parts in theleast/time and at a minimum cost.

Further objects and advantages will ap-l pear from the detaileddescription hereinafter referred to.

The invention consists of structural features and relative arrangementofthe different parts comprising the inv` ntion which will behereinafter more fully described and particularly pointed out in theappended claims.

In the drawings in which similar reference characters indicate the sameparts in the several figures of drawings.: Figure 1 is a side view ofthe cooker, partly in longitudinal section to show the interiorconstruction Of the barrel; Fig. 2is a plan view, partly in section toshow the interior of the barrel; Fig.v 3 is an enlarged sectional viewof the cooker at the outlet end of the barrel; Fig. 4 is a section online 4-4 of Figs. 1 and 3; Fig. k5 is a section on line 5-5 of Figs. 1and 3;,and Fig. 6 is an enlarged fragmentary section of a coupling ordiaphragm of the inner steam spray pipe'fshaft.

In the drawings, l, 1, are structural steel pedestals or base sectionsand braces, Which rigidly support and firmly hold the imperforate,container barrel 2, .having the inlet -head 3, and outlet or dischargehead 4; said barrel 2,. being provided With the feed neck for theattachment of inlet chute 5 for feeding Iof the material, and manholesand co-vers 6, for access to the interior of the barrel to permitexamination, adjustment and repair of all parts vWithin the same.

7 is a discharge opening in the lower side of head 4, having a pivO-teddoor plate 8 for varying the size of discharge opening 7.

Base pieces 9 are provided with cross pieces 10 and braces 11, forrigidly supporting the journalboxes 12 carrying the shaft 13, of thedriving gear, to be presently described. Fastened to said shaft 13 is aclutch' 21', controlled by a lever 22, saidv wheels 19 and 20 beinggeared to Wheels 14 =and 15, by

25 represents' a perforated, rotatable steam 'spray' pipe shaft Withinthe barrel 2, v,preferablyv at the out-let end and which `passes at oneof its ends through a suite .able opening and packing inthe dischargehead 4, While its other or inner end rests in.

diaphragm 28 which is rotatably supported in a bearing 26, fixed to theinside of the barrel, as shown in Figs. 2 and 5.

27 y's a 'section of a perforated steam spray pipe shaft formingacontinuation of the section 25, and separated therefrom by .adiaphragm28, and 29 is a similar section extending from the end of section 27 andseparated therefrom by the diaphragm 30. Said section 29 passes throughan opening, provided with steam tight packing, in the inlet head 3, andis provided on its outer end with a solid removable cap 31. Each of saidsections 25, 27 and 29, are provided with suitable perforations 32 forthe purpose of permitting steam or other heating or cooking medium topass from the interior speed, and a means of Well known sprocket .chains23 and 24, as shown. f

of said sections into the interior of the barrel 2, and each of saiddiaphragm sections 28, and 30, rest in bearings 2G, thereby rotatahlysupporting the full length or sections of spray lpipe shafts 25, 27 and29, properly and equidistant fromthe inner wall of the barrel.

32, 32', are combined miXers and conveyer paddles arranged radially andsecured to the different sections of the rotary spray piper shafts 25,27 and 29, and rotate with the same, for the purpose of not onlythoroughly mixing and agitating the material fed into the barrel 2, bythe feed chute 5, but also convey the said material through the barrelfrom right to left, and finally out through the discharge opening 7, tobe received in any suitable conveyer, through 33.

34 is a stationary steam distribution cylinder, rigidly held andsupported by means of a standard 35 secured to the base pieces 9, and isclosed at its outer end by a removable cap 34', and open at its innerend to snugly receive the outer and imperforate end of the rotatablespray pipe section 25, which passes through `a suitable opening andpacking in the discharge head 4, as shown in Fig. 3. Surrounding andsecured to the outer end of section 25 and interposed between the drivegear 17, and head 4, and abutting against said head, is a thrust collar36.

37 is a central imperforate rotary steam pipe, leading from the interiorof section 29, through the diaphragms 30 and 28, sections 27 and 25, andhead 4, to the interior of the forward end of the steam distributioncylinder 34, and passing through and connected to a piston 38, revolvingin said cylinder 34. Connected at one of its ends to the diaphragm 28,and situated within the spray pipe shaft 25 and surrounding the pipe 37and separated therefrom is a second rotary steam feed pipe 39,. whichalso passes through the head 4 and into the cylinder 34,

and is also connected to a rotary piston 40, in the same manner as pipe37, and as shown in Fig. 3.

The rotatable, perforated spraying pipe shaft 25is extended through thehead 4 and thrust collar 3G, by an imperforate section. whose outer endsurrounds the pipe 39 and also is separated therefrom, and is rotatablysupported in theopen end of the cylinder :34 which is provided with agland 41 to insure a tight joint between the said shaft 25 and `cylinder34.

42 is a main steam supply pipe which in the present invention isprovided with three branches 43, 43 and 43, each having its owncontrolling valve 44, 44' and 44, respectively, and lead into thecylinder 34 on different sides of the pistons 38 and 40, as shown, sothat pipe 43 communicates with the interior of pipe 37, pipe 43 with 39,and pipe 43 with spray pipe shaft 25t 45, 45 and 45 are drip pipesconnected with the bottom of the cylinder 34 on different sides vof thepistons 38 and 4() and are controlled by suitable valves, and lead to acommon drain pipe 4G, for the purpose of withdrawing any wateraccumulated in the cylinder34,due to condensation of the steam.

47 represents a lagging which may be placed on the outside of the barrel2 for the purpose of insulation, and for retaining the heat within thebarrel.

lf it is desired, the pitch of the paddles 32 may vary from the inletend toward the outlet, and preferably are so arranged that the paddlesattached to section 29 will cause the material to travel faster than thepaddles of section 27, and paddles of section 25 advance the materialslower than the paddles attached to section 27.

While I have shown and described three spraying or heating sections, 25,27 and 29, l do not care to limit myself to this exact number, as thisnumber could be varied more or less, without departing from theessential features of my invention. Furthermore, while l have Shown theconveyer paddles attached to the rotary spray pipe sections, this is notessential for carrying out the invention, as the conveyer fiights may beattached to the barrel which can be rotated, and the pipe section so asto be stationary, as will be readily understood by one skilled -in theart, but I have herein illustrated my preferred form.

The operation of the apparatus is as followsz-They uncooked material isfed at a uniform rate into the chute 5, and the clutch 2l is thrown soas to engage either of the sprocket wheels 19 and 20, depending on whatspeed it is desired to rotate, by means of intermediate shaft 12 andgears 16 and 17, the inner spray pipe sections 25, 27 and 29, with theirattached conveyer paddles 32.- The live steam is admitted into thedifferent sections 25, 27 and 29 by openingV the valves 43, 43 and 43,and the amount of steam issuing through the openings 32 of each of saidsections into the barrel 2, is separably and independently controlled,depending upon what valve is operated. The material within the barrel isagitated by said paddles 32 and conveyed through differentzones of heatand steam density, moving along the section 29 at a certain speed, thenslower at section'27, and slowest at 25. Thel maximum of cooking iseffected at section 29, owing to great capacity or volume of steam insaid section 29 as compared with that of section 25, and by openingthevalve 43a greater quantity of steam can be admitted in said section29. The spray section 25, by properv adjustment of valve 43 can controlthe steam to such an extent as to cause a portion of pipe section 25 toact as a hot baking pipe beforeV the material is finally l'll dischargedout of the opening 7 into the conveyer 33. In order to 'control thesteam pressure and spraying in the section 27 one adjusts .the valve 43.From this method of operation it will be seen that by means of saidvalves 43, 43. and 43, the quantity or pressure of steam in sections 25,27 and 29, can be simultaneously or independently controlled of eachother, and Without interfer-ing `with the operationof the machine,

and so regulate and absolutely control the cooker too rapidly, theclutchl 21 can be thrown from engagement with the sprocket Wheel 20, tothe Wheel 19, and if a higher speed is desired, the clutch 21 is movedfrom the wheel 19 to engage 20, thus a further condition of regulationof the material is had in addition to the control of temperatures andsteam supply, as above explained.

From the `foregoin disclosure of construction and lmode o operation ofthe invention, it Will be seen that the apparat-us is capable of cookingmaterial of variable quality continuously and progressively, with aneconomical use o f the steam, and at vthe same time produce a better anduniform product in one apparatus in continuous operation; and allregulations of the operations being accomplished Without interruptions.to the apparatus. the steam distributing pipe 37 within the sections25, and 27, and pipe 39 within section 25 and the pipe 37, and saidpipes 37 and 39 leading to fa common distribution cylinder 34,. this'enables the valves 44, 44 and 44, respectively contro-lling the steam ofthe sections 29, 27 and 25, to be placed in such proximity to each otherat the dischargel end of the cooker, as to be quickly and read.- ilycontrolled at one point of the cooker by a single person, Without beingrequired to move from his position at 'the discharge end, whileobserving the vmaterial passing out of the opening 7, and in thisrespect differs and has great advantages over priorcookers, in which thepipe sections and steam connections are so arranged that a person isrequired to travel from one place toanother, up and down the full lengthof the cooker, in order to cont-rol the different sections.
